STEAM APPLICATOR FOR'WALL-PAPER-REMOVING APPARATUS.

Application filed June 21, 1926. a Serial 170,117,397.

My present invention has for object to cate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a applicator; 1

Fig. 2 is a perspective back view of the same, with the handle shown in a different position by means of broken lines; I

Fig. 3 is a fragmentary detail view in transverse section taken on the line 3-3 of Fig. 1 on an enlarged scale;

Fig. 4 is a fragmentary detail view in longitudinal section taken-on theline 44 of Fig. 1, on anenlarged scale; v j b Fig. 5 is a fragmentary detail view partly in sideelevation and partlyin section taken on the line .55 of Fig. 2, on an enlarged scale; and V l Fig. 6 is a fragmentary detail View in section taken on the line 66 of Fig. 1, on an enlarged scale;

' The numeral 7 indicates a sheet metal casing in the form of a shallow pan, the sides of which at the open face of said casing have a relatively deep endless channel 8 in which is mounted an endless combined insulating and joint strip 9 of rubber or other suitable Said channel 8 is. outside ofv the sides of the casing 7 and the strap 9 projects outwardly from said channels. A handle '10 is securedto the back of, the casing 7 by an L-shaped. bracket 11 the perpendicular member of. which comprises two overlapping sections connected by a slot and nut-equipped bolt connection 12 arranged to permit lateral swinging movement ofthe handle parallel to the back of the casing 7. Said sections of the bracket 11 are held aligned by a notch and lug connection 13. The members of the connection 13 are held interlocked by the nut-equipped bolt of the connection 12, as shown by full lines in Figs. 2 and 5.

Within the casing 7 is a transverse hollow reinforceing rib 14 secured to the back of said casing with its ends secured to and closed by the respective sides of said casing. This rib 14is located midway between the top and bottom of the casing 7 and affords a perspective face view of the steam distributing chamber 15, and it will be noted that the depth of said rib is less than that of the sides of the casing 7. A'

corrugated metal. sheet '16 is secured in the casing 7 on each side of the rib 14 with its corrugations extendlng longitudlnally of said casing and transversely of said rib.

Each sheet 16 completely fills the respective section of the casing 7 in which it is secured.

The inner ends of the corrugations inthe sheets 16 are closed by the sides of the rib 14 and the outer ends thereof are secured to and closed by the respective sides of the casing 7. The inner ridges of the corrugations in the sheets 16 rest on the backof the casing 7 and are secured thereto. Y The corrugations closed by the back of the casing 7 afford laterals 17 with which the steam distribut ing chamber has communication through holesi18 formed in the sides of the rib 14. In the outer ridges of the corrupations in the sheets 16 are a multiplicity of longitudinally spaced orifices 19 for the discharge of steam from the laterals 17 through the open face of the casing 7.' The depth'of the laterals 17 -is considerably less than that of the steam distributing chamber v15.

A steam pipe 20 is laid in the central outer corrugation in the lower sheet 16 and extends through holes in the lower side of the casing 7 and the lower side of; the rib '14 and is rigidly secured thereto. Thissteam pipe 20 extends below the bottom of the casing 7 to afford asteam hose connection leading from a steam generating apparatus, not

shown.

" In the lower end of the casing 7 is a shal- I low trough 21 forthe collection of condensed steam which takes place outside of the rib 14 and corrugated sheets 16. Steam conveyed from the generating apparatus, not shown, to the distributing chamber 15 from the steam pipe 20 enters the laterals 17 from said chamber through the holes 18 and escapes through the orifices 1%) in jets directed through the open face of the casing 7. In removing wall paper from a wall the applicator is held by the handle 10 with its open face turned toward the wall and with its combined insulating and joint strip 9 pressed against said wall to close the casing 7 and confine the steam discharged from the orifices 19. The jets of live steam from the laterals 17 are directed against the wall paper and upon striking the same are condensed and quickly penetrate the paper" and loosen the same from the wall. The dead steam in the casing 7 alsomaterially assists in loosening the paper from the wall.

The arrangement of the laterals 17 and their orifices 19is such that-thesteam: is

applicator and the wall, and it also acts asv an insulator to protect the woodwork from the hot sidesof the casing T and further prevents the escape of steam against the woodwork. 7

The rib 14 and corrugated sheets 16 greatly strengthen the apar-atus so .that the same may be made from relatively light materiahand the applicator .will not budge or warp under steam pressure in the distributingchamber and laterals 17. Due to the converging lines of the laterals 17 there is no chance for the collection of condensation therein and said condensation will be blown, from. the laterals 17. through theorifices 19 and any condensation that takes place out-( side ot' the rib l4 and corrugated sheets 16. y ep':

will be collected inthe trough 21. ing the applicator tree from condensed steam, no extra weight is' added thereto, so that the same may be easily handled by the operator. Thepurpose of making the handle adjust-able is to. permit said handle to be turned into a. position asindicated by dotted lines in Fig. 2 so that the, applicator may beused back of a radiator or the like.

"What I claim is:

1..An applicatorof the kind described comprising a. casing, a hollow reinforcing rib afiording a steam distributing chamber, a connection for a steam supply member on said'chamber, a corrugated sheet in said. case ing having its corrugations closed by the back thereof to afi'o'rd lateral steam conduits each having one end in communication with said chamber and the other end closed, said conduitshavinga plurality of orifices for the escape of steam..

. by the V J steam conduits,the innerends otwhich have communication with said r1b and the outer 2:"An applicator of the kind described comprising a casing, an intermediate hollow reinforcingrib affording a steantdistributing chamber, a connection for a steam supply member on said chamber, and a corrugatednshect :in the casing on each side of said rib, the corrugations in said sheets being eX- tended transversely of said rib and closed ,back of the casing to aflord lateral endsot'which, are closed, said conduit-s havinga plurality of orifices for the escape of steam.

3. The structure defined in claim 2 in:

which said connection lSiH the form of a pipe which adapted to beplaced against a wall, a steam distributing chamber in the casing extending the full'length thereoi, and closely "positioned lateral steam conduits leading from the distributing chainber and completely filling the casing, 'said chamber having a connection for-a steam supply member, and said conduits having a plurality of orifices for the escape of-steam'."

5."*A1i "applicator ot the =ki'nd. described comprising a casing having an i open :face adapted to be placed against a wall, a steam distributing chamber: in the :casing 1 extending the full length thereof and provided with a connection for a steam'fsupply mem her, and a corrugated-sheet in-said: casing having its corrugations longitudinally closed by the backthereof' to form'closelypositioned parallel lat-eral'steamcondu-its, one of the ends of said conduitsbeingin communication with said chamber" and the other. ends being closed, 3 said conduits completely filling the chamber andhavinga plurality of orifices'for ;the"esca1pe of steam;

In testimony whereof I affix my signature.
